Abstract (en)
[origin: US2009233052A1] A communications cable is provided comprising a conductor and polymer insulation encasing said conductor, the polymer insulation having a foamed interior and having an exterior surface formed from longitudinally running rounded peaks and valleys. A process is also provided for producing this polymer insulation or unfoamed polymer insulation having the same or similar peak/valley exterior surface by extruding molten thermoplastic polymer through an orifice to coat a conductor passing through the orifice, thereby forming polymer insulation on the conductor, said orifice defining the exterior surface of said polymer insulation comprising longitudinally running rounded peaks and valleys, said peaks covering at least about 30% of said exterior surface and having a height that is at least 50% of the width of said peaks.
